lation and is otherwise even ; it shows black venular points ; the line 

 itself is double and these black points contrasted with the pale yellow 

 included space. The pale yellow s. t. line is thrice waved. This species 

 is allied to S. Graefiana, from which it may be distinguished by its smaller 

 size, its more even wings, which want the terminal festooned line, its paler 

 ground color, straighter median shade, smaller orbicular spot and more 

 prominent subterminal shade. The hind wings are very pale yellow and 

 show a faint subterminal reddish shade in addition to the faint and more 

 irregular mesial line. Beneath this subterminal shade is indicated by 

 fragmentary reddish scales superiorly on both wings. In Pettiti the mesial 

 line on secondaries beneath is more flexuous centrally.

Although Mr. Stretch, in his " Bombycidse of North America," gives 

 Behrensii {fig. 6) as distinct from montana (fig. 7), large material, sent by 

 Mr. Behrens, makes me believe that they are opposite sexes of the same 

 species, which should retain the name Behrensii. The orange salmon- 

 colored Behrensii seem to me the males, and specimens vary from the form 

 described by Mr. Stretch, in which the insect is nearly concolorous, to the 

 more usual form where two silvery fasciae break the monotony of the 

 wing. The bands composed of light colored spots are more or less 

 visible in the males ; in the females (= montana) with fuscous wings, they 

 are more evident. One intermediate specimen ( ^ ) is faintly tinged with 

 reddish. The hind wings have the margins and veins orange in Behrensii; 

 in the $ (montana) the wing is all fuscous, but this latter tint can be 

 seen in the ^ on the interspaces. 



I have examined the species described by Mr. Behrens (Can. Ent., 

 viii., 174). I think that the specimen alluded to but not separately 

 named under the description of sequoiolus is the female of that species, fol- 

 lowing out the idea that the sexes differ more than usual in Behretisii, to 

 which sequoiolus is allied. The form described by Mr. Behrens as Baroni 

 seems to me distinct and not the opposite sex of mendocinolics. It may 

 be known by the bands remaining grayish fuscous, while the interspaces 

 are shaded with red, not orange. But if the silver bands are a male char- 

 acter this opinion may need revision. The small species Lenzi, and the 

 larger sequoiolus^ can be readily recognised from Mr. Behrens' description 

 of them ; while niendocinolus seems to differ from ^ Behrensii by the 

 smaller size, fuscous hind wings and less brilliant color of the primaries.
